You should meet my exercise buddy

I have this lovely dog called Moose. He's a sort of English Bull Terrier mixed with a few somethings, one of which might be pit bull. He's actually quite small and doesn't have a vicious bone in his body.
He's probably one of the stupidest dogs I've ever had!
That's a bit mean, because he's actually pretty easy to train. But he's very scatty and a bit nervous - we still had our big dog when he was a puppy and she was very dominant, which probably explains it.
But if you're nice to him, he sneezes! Seriously.
He has absolutely no idea what a ball is. If you throw one for him, he looks at you like 'What did you throw that away for? Don't you want it?' Won't even go and sniff it. Sticks get the same response.
But I love him and he's my exercise buddy.
As soon as I get home for work at night, I get into my gear and off we go. Anywhere between 4km and 5km, depending how much time I've got and which route I take. A couple of reasonable size hills to get the heart rate up, and the hills are getting easier all the time.
Moose has a lovely time and is very good - sits down before we cross the road, doesn't pull on the leash (unless he sees a cat) and gives me the occasional adoring look.
But I don't like it when people want to pat him as we walk by. I just can't handle the look on their face when he sneezes on them.
